Application filed February 9,1933. Serial No. 2163281.

To silica/tom it may concern:-

Be it known that l, l VALTER C. Goren, a

citizen of the United States, residing at ll/larionville, 1n the countyof Lawrence and State of Missouri, have inventednew and usefulImprovements in Inner-Tube Protectors of which the following is aspecificstion. V

This invention relates to pneumatic tires,

particularly to armor therefor, undhes for- .its object the provision ofe, protective armor permanently associated with the outer casing anddisposed between the casing and the inner tube whereby sharp objectspenetrating the casing will be deflected and consequently prevented frompuncturing the inner tube.

An important object is the provision of an internal armor of thischaracter so constructed esto be yielding whereby the resilience of thetire will not be decreased,

A further object is the provision of such i an armor so equipped withprotective coverings that chafing-of the tube and the casing will beprevented.

With these and other objects in view such as simplicity, comparativecheepness, thorough efiiciency and the general improvement of the artthe invention consists in the construction and arrangement of parts tobe hereinafter more fully described and claimed and illustrated in theaccompanying drawings in which,

Figure l is side elevation of it tire casing having my armor appliedtheneto Fig. 2 is a cross sectional view therethrough,

Fig. 3 is u longitudinal sectional view on the line 3--3 of 2,

Fig, i is a similar view on the same line but looking in the oppositedirection,

Fig 5 is a detail longitudinal sectional View on the line tie-5 of 2,and

Fi 6 is a lan view of a sin is section 22 r. a before bending into aienate form.

Referrin more iaiticularl to the draw ings, A. deslgnates a tire casingof any w elli known or preferred type,- though for purposesof'illustration l have shown it as being of the kind ommonly knqiwn asstraightside if 5 y In carrying out my invention 1 provide a band 10disposed upon the inner side of the casing against the tread portion andcurved transversely to conform to the curvature oil casing, This bend ismerely placed within the casing and is not secured there to. Secured tothe casing is a series of in terfitting and interlocking spring sectionseach comprising a strip 11 of spring steel bent into arcuate 'form, asshown, and having one edge offset as at 12. The offset portion 12extends entirely to one end offlthe strip but terminates short of theother end. The same side edge of the strip is provided with an earoffset in a direction opposite to that of the portion 12, the ear 13being between one end of the offset 12, and the adjacent end, of thestrip: From the ear 13 to the adjacent end the strip 11 is reduced inwidth as shown at 14:and has its end portion notched as shown at 15 andbeveled as shown at 16 for providing a tine 17.

After the band 10 is placed in the casing, the curved strips 11 areassociated with the casing with the ofi'eet 12 of one strip lyingagainst the outer side of the adjacent strip, the stripsbearing againstthe band 10 to prevent chafing of the casing. The ear 13 on each stripbears against the inner face of the eidjaceh t strip. The reducedportions 14' of the st *3 are passed under the head at one the casingand bent upwardly to lie a list the outer side thereof with the tines l;bent at right angles to the body of V the assembled strips as aprotector to prevent chafing of the inner tube.

From the foregoing description and a study of the drawings'it will beapparent that l have provided a protective armor for application withina tire casing which will eihciently deflect sharp objects penetratingthe casing, thereby preventing punctures of the tube. The interlockingstrlpstwill also serve to strengthen the casing against danger ofblowouts and also minimize the risk of rimcuttingl in case the tire isused in an under-inflated condition,

lit will be of course understood that I rewill serve the right to makesuch changes in the construction and arrangement as will fall Within thescope of the 'matter claimed.

Having thus described my invention, I claim: i

1. In combination'with a tire casing, an internal protective armorcomprising; a pinrality of similar metallic sections disposedtransversely aainst the inner periphery of the casing and curved toconform thereto, each ofsaid sections having one end free and the otherend bent under the bead of the casing and secured upon the outside ofthe casing, an ofi'set portion on each section overlapping the nextadjacent section, and

an ear on each section ofi'set' oppositely to and in the same directionas said first named offset and engaging the next ad acent section, saidears and said sections being pro vided at their points of contact withinterengagmg depressions.

2. In combination with a tire casing, an

internal protective armor comprising a pluriphery of the casing andcurved toconform thereto, each of said sections having one end free andthe other end secured to the casing,

and an car on each section ofiset and engaging the next adjacentsection, said ears and said sections being provided at their points ofcontact with interengaging depressions.

3. Incombination with a tire casing, an internal protective armorcomprising a plurality of similar metallic sections disposedtransversely against the inner periphery of the casing and curved toconform thereto each of said sections having oneend -freeanci the otherend secured to the casing, an offset portion on each section overlappingthe next adjacent section, and an car" on feachv section oflsetoppositely to and in the same direction as said firstnamed oifset andengaging the neXt adjacent section.

In. testimony whereof I afiix my signature. WALTER C. GUILD.
